Science
Mechanism of Action
This mineral functions as a physical abrasive, effectively removing surface impurities through a grinding and polishing action. Its needle-like crystal structure may also contribute to texturizing and exfoliating effects on the skin.

Dusting Analysis
No specific data indicates wollastonite is commonly 'dusted' at ineffective levels; however, as a particulate, proper formulation ensures use at concentrations appropriate for its intended abrasive function.
The Formula
Formulation
Stability
Wollastonite exhibits high chemical resistance, thermal stability, and is chemically inert, maintaining its integrity within formulations. It also demonstrates low thermal expansion and is non-magnetic.
Conflicts
- Potentially incompatible with highly acidic ingredients due to its inherent high alkalinity (pH 10-11), which could affect the stability or efficacy of pH-sensitive components in a formulation.
Safety
Safety Profile
The CIR Expert Panel deems silicate ingredients, including wollastonite, safe for cosmetic use when formulated to be non-irritating. However, data is insufficient for naturally-sourced silicates in products with potential incidental inhalation.

Verdict
Given the lack of specific clinical studies demonstrating efficacy beyond general physical abrasion and unknown skin compatibility data, its overall value in precision skincare remains to be fully established.
